. it is herein disclosed as embodied in a construction particularly adapted for use H1 winders of the type illustrated and described in my copending application Serial No. 628,474, filed May 20, 1911, now Patent 1,175,710. As to the broad subject-matter common to the present application and said application No. 628,474, the'present case is a continuation or division of the earlier application. Certain subject-matter is also disclosed inapplication Serial No. 809,797, filed Dec. 31, 1913, now Patent No. 1,268,684..

In the accompanying drawings, Figure 1 is a longitudinal central section through a support embodying the features of my invention, a yarn carrier being shown as being locked in operative position upon said support. Fig. 2 is a fragmental sectional view illustrating the operation of withdrawing and unlocking the yarn-carrier. Fig. 3 is a transverse sectional view taken in the-plane of dotted line 33 of Fig. 1. I

In the drawings, a indicates a body of yarn wound upon a yarn-carrier 1. While the present invention is adapted to be used in connection with yarn carriers of various forms, I have herein shown a cylindrical tubular yarn-carrier formed of two cylindrical sheet-metal sections 2 and 3 rigidly secured together, each of said sections having an annular end wall 4. In each of the end walls 4 is a central opening surrounded by an inturned flange 5. Between these flanges extends a sleeve 6. The inner end of one of the flanges 5 constitutes an annular locking cient clearance between said latch and the sleeve 6, spacing rings 8 are interposed between the ends of the sleeve and the flanges 5.

The support upon which the yarn carrier l is rotatably, mounted may itself be supported in any suitable manner. Herein I have shown the support as mounted upon-an arm 9 corresponding functionally to one of the arms 8 shown in said application Serial No. 628,474. Upon a pivot or spindle 1O fixed to the arm 9 is rotatably mounted a hub 11. If desired, ball-bearings may be provided between the spindle and thehub, as herein shown. In the present embodiment the hub comprises a central sleeve 12 upon one end of which is mounted an annular member 13 having a flange 14 which encircles the end of the sleeve 12.

The end of the sleeve is expanded to 'hold the member 13 against longitudinal ball race 15. Said member has a cylindrical portion 16 and an-annular stop flange 17.

Upon the other end of the sleeve 12 is mounted a member 18 having an annular fiang 19 which surrounds the sleeve. The mem-er 18 comprises a ball race 20, and a cylindrical portion 21 having an annular shoulder 22. A sleeve 23 is confined between the stop flange 17 and the shoulder 22, the parts 12, 13, 18 and 23 being rigidly secured together by means of a tubular plug 2 24 screwed into the end of the sleeve 12, said, plug having an annular outwardly extending flange 25 that bears against the member 18. The interior of the plug 24 may be of polygonal form to receive a wrench.

A sleeve 26 fits upon the inner portion of i the spindle 10 and is provided with a cone 27 A series of balls is located between the and the cone 29. The two ball-bearings just described are locked in adjusted position by means of a nut 30. 31 is a washer between the sleeve 28 and said nut.

Lubricant is retained within the ballbearings, and dust excluded, by suitable .means.

Herein is shown a sheet-metal closure 32 fitting within the outer end of the cylindrical portion 21. At the inner end of the hub is a disk 33 of suitable material, such as felt, said disk lying at the inner side of a being properly wound upon the yarn-carrier, more or less yarn will be wound upon the yarn-carrier support adjacent to the arm 9. To prevent any such yarn from in contact with the getting into the space between the hub 11 and the arm 9, or between the hub and the yarn-carrier, I provide a spool 35 comprising end flanges 36 and 37, said spool being fixed upon the sleeve 23 adjacent to the stop flange 17. As shown in Fig. 1, the arm 9 and the adjacent end of the yarn-carrier 1 are recessed to receive the spool flanges 36 and 37, respectively, so as to insure that any strand drawn between the yarn-carrier and'the arm 9 shall be wound upon the spool 35. e

The yarn-carrier l is adapted to fit'upon the sleeve 23. The .spool flange 37 constitutes a stop for the yarn-carrier. The yarncarrier is releasably locked against withdrawal from the hub 11 by a device comprising a locking slide 38 reciprocable longitudinally of, and free to tilt slightly in, the hub.

The slide 38 has a latch finger 39 which projects through an opening 40 in the hub and is adapted to lie adjacent to the annular locking shoulder 7 of the yarn-carrier 1.

The slide 38 is normally held in the posisleeve 23.

In operation, the operative slips a arncarrier 1 upon the hub 11. The latch nger.

39 is depressed by the inner flange 5 as the yarn-carrier is pushed against the stop flange 37, and springs up into locking position'as soon as said flange 5 has passed it.

When the formation of a yarn mass on the yarn-carrier 1 has been completed, the operative takes hold of the yarn mass and draws it longitudinally of the hub 11, the latch finger 39 being forced longitudinally of the hub by the locking shoulder 7 against the pressure of the spring -11. The finger 39 is inclined so that when it is forced I against the end wall 46 of the opening 40, said finger is forced toward the axis of the hub, the slide 38 tilting to permit of such movement of the latch finger.

I claim as myinvention:

1. A yarn-carrier support having, in combination, a hub having an opening therein, a slide in the hub having a latch finger projecting through the opening, a stop lug on the slide projecting through an opening in inner surface of the the hub, and a spring arranged to act upon the slide to yieldingly hold the latch finger in operative position,'said finger having an inclined surface arranged to coact with a portion of the hub to cause withdrawal of jecting through the opening, a stop member on the hub arranged to coact with the latch finger to look a yarn-carrier on the hub, and a. spring arranged to act upon the slide to yieldingly hold the latch finger in operative position, said finger having an inclined surface arranged to coact with a portion of the hub to cause withdrawal of the latch finger when the slide is moved against the pressure of the spring.

3.
